Evaluation of dynamic properties in ABS and PLA thermoplastics across frequency ranges.

ABSTRACT: Additively manufactured thermoplastics are increasingly employed in vibration-sensitive applications across the automotive, biomedical, and aerospace industries, where mechanical performance under dynamic loading is critical. This study provides a novel integration of Dynamic Mechanical Thermal Analysis (DMTA) with frequency response function (FRF) evaluation to capture the sub-glass-transition viscoelastic behaviour of 3D-printed ABS and PLA within 5-100 Hz range, a comparative approach not previously reported in the literature. The narrow 35-60 °C range was selected to focus on sub-Tg behaviour relevant to service conditions at which applications include vibration control in automotive panels, biomedical housings, and electronic enclosures. Unlike prior DMTA-only studies, this work combi
